ATENT HINGE.

SPECIFICATION forming part of Letters Patent No. 788,051, dated April 25, 1905.

Application filed July 1, 1904. Serial No. 214,945.

To all Mil/0m it may concern:

Be it known that we, CALVIN Knirn and Gnousn F. LISTER, citizens of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements-in Hinges; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in universal lock-hinges.

It has for its object to provide a hinge which may be visible or invisible and adapted to be locked or held rigidly in place at different points in its circuit.

The invention consists in the details of construction and combinations of parts hereinafter described, and more particularly pointed out in the claims concluding this specification.

in the accompanying drawings, illustrating the preferred embodiment of our invention, Figure l is an elevation of our hinge applied to a door, the front plate being removed, (lisclosing the. interior mechanism and the out line of the door and frame in dotted lines. Fig. 2 is a central vertical sectional view through the hinge and supporting device. Fig. 3 is an elevation showing the mechanism of the hinge when the door is opened to an angle of ninety degrees, parts of the door and frame being broken away; and Fig. 4: is a perspective view of one of the spring-pressed arms or jaws.

Referring more particularly to the drawings, in carrying out our invention we provide a frame 1, adapted to be attached to one of the lower corners of a door, as shown. A disk or plate 2, fixed to a pin 3, is mounted above an opening in said frame, said pin extending through said opening and engaging the floor-plate l. Said floor-plate has semicircular raceway 1 for ball-bearing around its upper edge, and an upper bearing-disk 5, fixed to the frame, has a supplemental groove or raceway 5 in its lower surface.

To the upper surface of the disk 2, near opposite sides thereof, are mounted roller-sleeves 6 around screws7. If desired, a yoke or crossbar 8, secured to the disk 2 at its center and having oppositely-extending arms 9, each projecting above one of said roller-sleeves, may be used or the roller-sleeves with their securing-screws may be arranged separately. lVithin the rectangular portion of the frame are pivoted two op1')ositelyfacing arms or jaws 10, provided with wide lower ends with vertical grooves 11 about centrally thereof. Said lower ends of said jaws are preferably about as wide from back to front as shown in the drawings as the diameter of the disk 2, so that they will at one position of the door engage both roller-sleeves, as in Figs. 1 and 2. \Vhen the door is pushed, as in opening the same, the jaws are forced apart by the rollersleeves, so that the jaws engage said sleeves separately until the door has been rotated on its pivot or axis one hundred and eighty degrees. The upper ends of said jaws may be smaller and of less width, as shown, and are each preferably provided with a perforation 13 with another smaller opening 12 therein. A spring 1% is arranged between said jaws, having each end inserted through the perforation 13 into the opening or socket 12 of one of said jaws.

It will be readily seen that when the door is opened the lower ends of the jaws will be forced apart by the roller-sleeves until said sleeves engage the central grooves in said jaws, when the door will be locked or held in that position until it is either pushed back to its former position or further around. l/Vhile we have shown our hinge arranged at one side of the door, so that it can open either way or remain in said closed position, said hinge may be used on revolving doors, in which case the door may be held rigidly at each ninety degrees in its circle of movement.

\Ve are aware that changes may be made in our invention without departing from the spirit or sacrificing the advantages thereof. For instance, a different form of spring from that showna fiat one, for example-may be used, and the form of the jaws or arms may be varied. \Ve therefore reserve the right to make such changes as fairly fall within the scope of our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A hinge comprising a frame adapted to be pivotally mounted upon a fixture, a pin having a disk arranged within said frame, said pin extending through said frame and secured to said fixture, oppositely-arranged roller-sleeves on said disk, and spring-pressed jaws adapted to engage either one of said roller-sleeves separately or both at the same time.

2. A hinge comprising a frame adapted to be pivotally mounted upon said fixture, a pin having a disk arranged within said frame, said pin extending through said frame and secured to said fixture, oppositely-arranged pins on said disk, roller-sleeves mounted on said pins, and spring-pressed jaws, each having a centrally-arranged groove adapted to engage said 1 roller-sleeve.

3. A hinge comprising a frame adapted to be pivotally mounted upon the fixture, a pin having a disk arranged within said frame, said pin extending through said frame and secured to said fixture, oppositely-arranged pins on said disk,roller-sleeves mounted on said disks, jaws pivoted to said frame and each having a perforation with a socket-openingth'erein, and a spring having each of its extremities extend: ing into the perforation and engaging the socket in one of said jaws.

4:. A hinge comprising a frame, a pivotal bearing comprising a floor-plate and a ring secured to said frame, a pin having a disk arranged within said frame, said pin extending through said frame and engaging said floorplate, oppositely-arranged pins on said disk, roller-sleeves mounted on said pins and springpressed jaws adapted to engage either one of said sleeves separately or both at the same time whereby the door is held rigidly at different points in the circle of movement.

In testimony whereof We aflix our signatures in presence of two witnesses.
